Liquidity Trap - Criticisms

Criticisms

Austrian School economists generally argue that a lack of investment during periods of low interest rates are the result of malinvestment and time preference instead of liquidity preference. Most Austrian economists have rejected Keynes' theory of liquidity preference altogether. In his book America's Great Depression, Murray Rothbard argued that interest rates are determined by time preference. Says Rothbard, "Increased hoarding can either come from funds formerly consumed, from funds formerly invested, or from a mixture of both that leaves the old consumption-investment proportion unchanged. Unless time preferences change, the last alternative will be the one adopted. Thus, the rate of interest depends solely on time preference, and not at all on "liquidity preference." In fact, if the increased hoards come mainly out of consumption, an increased demand for money will cause interest rates to fall — because time preferences have fallen."
